[Zope] Enhanced user tracking and security products in zope?

[Exteam]

Hi

I have just completed a demo site in Plone, and would
like to know which pages, my users are interested in,
how much time they spend on pages, which links they
visit (and from where) etc.
 
In order to do this, I am looking for some zope
product which allows - 
1) better user management than for eg with automatic
password expiry (based on usage etc).

2) indication of which pages were most frequented by a
certain users, clicks made, etc. 

Is there any product / software based on zope or plone
which can meet these parameters? even half way thru?

Any remarks will help...

Harish
